This article explains why static may be heard from iMac computers when making a dial-up connection.

Products Affected

iMac

Symptom

After making a dial-up connection you hear a static noise coming from the computer's speakers. The sound input source has changed to Internal Modem.


Solution
    1. In Mac OS 9, change the built-in input source from Internal Modem to Sound In using the Sound Strip portion of the Control Strip, or the Sound control panel.
    2. Lower the computer's sound volume.
    3. If you are using Internet Connect in Mac OS X 10.0, update to Mac OS X 10.1.

Notes
    1. The parenthetical product descriptions (Summer 2000) and (Summer 2001) refer to the summer of the Northern Hemisphere.
    2. The built-in sound input changes from the computer's current setting to Internal Modem when a dial-up connection is made so you can hear the modem connecting. This is normal. After disconnecting from the dial-up connection, the sound input source reverts to the previous setting.
